APPARATUS FOR PRINTING GARPETMYARNS.

SPECIFICATION forming part of Letters Patent No. 582,02 5, dated May 4, 1897. Application filed November 27, 1896. Serial No. 613,501. (No model.)

To all whom t may concern:

Be it known that I, VILLIAM SHAW, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Apparatus for Printing Carpet-Yarns, of which the following is a specication.

My invention refers to improvements in apparatus for printing carpet -yarns such as used in the manufacture of tapestry and velvet carpets, and more particularly to the class of appliances illustrated and described in my Letters Patent of the United States No. 543,512, dated July 30, 1895.

rl`he principal object of my invention is to provide suitable means for adj Listing and regulating the yielding or elastic pressure under which appliances for forcing liquid or semiliquid coloring-matter into yarn wound on a drum are conducted along such yarn after the coloring-matter has been applied principally to its surface by a color-wheel. The means for carrying out this object are more fully described hereinafter and set forth in the claims.

In the accompanying drawings, forming Apart of this specification and wherein like gures and letters of reference indicate corresponding parts throughout the different views, Figure 1 is a side elevation of a vertical standard in a proper guide and carrying a platform on which rubbing appliances in operative engagement with the yarn on a yarndrum are mounted in accordance with my invention. Fig. 2 is a ground plan of Fig. 1, and Fig. 3 a vertical section along line 3 3 in Fig. 1. Fig. e is a side elevation of a colorcarriage with a color-wheel and rubbing appliances mounted thereon in accordance with my invention.

28 is a bracket adapted to be attached to the main body of a 'color-carriage and carrying a vertical arm 60, which forms a bearing, within which a post 29, made ofrectangular cross-section, is made to slide. 30 is a hook attached to arm 60, to which the cord is to be attached used in drawing the color-carriage 12 forward and backward along the yarn Y on yarn-drum 33. Color-box 1 and colorwheel 23 are mounted on said carriage. Posts 29 are actuated by hinged levers 51, carrying rollers 49, which ride on a center rail 50, so as to produce operative contactvbetween the rubbing appliances and the yarn on the drum while said rubbing appliances travel behind the color-wheel. All these parts substantially correspond in their construct-ion and in their mutual relations and functions with the parts bearing corresponding characters of reference in said United States Letters Patent No. 543,512.

G5 is a platform at the upper extremity of post 29. 10, 11, and l2 are cylindrical studs screwed into said platform, and 14E 14': jamnuts for holding said studs in position..

15 is a pan for catching and carrying olf the drippings of coloringmatter from the equalizer 66 and the rubber 70, mounted at upper ends of said studs in manner hereinafter described. This equalizer 6G, to which may be attached an auxiliary rubber 88 and the main rubber 70, correspond as to their functions with the equalizer 6G and the rubbers 70 of aforesaid United States patents and resemble the same also as far as their general configuration is concerned. Equalizer 66 is provided near its forwardend with side lugs Z0 and Z' and with a rear lug Z2, and rubber 70 with side lugs 10 and lll and with a rear lug Z1?, in such manner that the upper end of stud 10 freely passes through lugs Z0 and Zw, that of stud 11 through lugs Z' and Z, and

that of stud 12 through lugs Z2 and W, so as to allow the equalizer and the rubber to freely play upward and downward along said studs. 13 13 are screws entering the heads of said studs and serv-ing by means of washers 14 to prevent the equalizer and the rubber from leaving said studs.

so, s', s2, S10, s, and S12 are U-shaped leafsprings yieldingly supporting, respectively, lugs Z0, ZZP, ZIO, l, and Zw. The lower ends of said springs are provided with perforations of sufficient size to permit the same to pass over the lower screw-threaded portions of studs 10, 11, and 12,while the perforations in the upper ends of said springs are of sufficient size to allow of the free play up and down of these ends along the studs.

I have found in practice that is is of much importance to be able to adjust the tension of the supporting springs under different parts of the equalizer and of the rubber in- IOO dependent of the tensions of the other springs or in certain relations with such tensions, and in accordance with the particular functions of the portions of the equalizer and the rubber which are more immediately supported by them. Thus if it should appear that too great an amount of coloring-matter is being applied to the yarn by the colorwheel and brought in contact with the equalizer and the rubber I can remedy this by increasing the tension on springs S10 and s, which will result in more firmly pressing the downwardcurving front end of rubber against the yarn and thereby pushing off and conducting downward such surplus coloring-matter. On the other hand, by increasing the tension on springs S0 and s I more iirmly hold the longitudinal arms a a of the equalizer against the yarn and thereby prevent the escape sideward of the coloring s matter forming the streaks applied to the yarn. If it should appear that the coloring-matter be not forced entirely through the yarn by the equalizer and the rubber, I remedy this by increasing the tension on rear springs S2 and 312. While it is intended to make corresponding side springs, as s0 and s and S10 and su, of the same configurations and to give them corresponding tensions, it often occurs that this can not be accomplished with sufficient accuracy in the manufacture and bending of these springs, and in this emergency it again becomes of much importance to provide simple means for producing proper tensions on these springs after they have been mounted on studs l0' and 11, and these adjustments I accomplish by means of nuts no, n', n2, n10, fn, and m12,

which support the lower ends of springs s0, s', s2, S10, s, and S12, respectively, and are in engagement with the screw-threaded lower portions of aforesaid studs. In screwing the nuts upward the tensions on the springs supported by them will be increased, while screwing them downward will reduce such tensions.

I have found in practice that providing the various springs be carefully. bent according to proper patterns, so that the tensions of each of the two springs on one of the studs bear a proper relation to each other, the upper adjusting-nuts n10, n, and 'am may be dispensed with and the lower ends of the smaller and interior springs 310, s, a-nd S12 may be made to rest directly upon the lower en ds of springs 510311 S12, respectively, in which case nuts no, n', and n2 will be utilized each in adjusting the tension of the two springs on the corresponding stud. Such a condition is indicated in dot-ted lines in the left-hand portion of Fig. l at s.

I claim as new and desire to secure by Letters Patent- 1. In apparatus for printing carpet-yarns, the combination with a yarn-drum and a color-wheel, of a rubbing appliance mounted on springs, and means applied to one of said springs, whereby its tension is adjusted independent of the tension of other such springs.

2. In apparatus for printing carpet-yarns, the combination with a U-shaped equalizer of a supporting-sprin g on each side of its front portion and a supporting-spring under its rear portion, and means applied to each of said springs, whereby its tension is adjusted independent of the tensions of the other springs.

3. In apparatus for printing carpet-yarns, the combination of a U-shaped equalizer, of a supporting-spring on each side cf its front portion and a supporting-spring under its rear portion, and means applied to the rear spring, whereby its tension is adjusted independent of the tension of the front springs.

4. In apparatus for printing carpeteyarns the combination of an equalizer, provided with two bars adapted to extend along the streaks of coloring-matter applied to yarn on a drum and a cross connection, of a rubber inserted between said arms, springs for supporting the front portions and the rear portions of the equalizer and of the rubber, and adjusting means applied to said front springs, whereby the upward pressure on said front portions is adjusted independent of that on said rear portions.

5. In apparatus for print-ing carpet-yarns, the combination with a U-shaped equalizer of a rubber inserted between its arms, joint screw-threaded guide-studs for said equalizer and said rubber near their front ends and their rear ends, supporting-springs for the forward ends and for the rear ends of the equalizer and of the rubber mounted on said studs, and nuts on said studs for independently adjusting the tensions of said springs.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 20th day of November, 1896.

VILLIAM Sl-IAV.
